The 96-tone Carrillo piano and the 31-tone Fokker organ will engage in both musical dialogue and confrontation throughout this concert. This will be expressed in a new work by composers Torsten Anders and Martin Lo-A-Njoe, written especially for this occasion. In addition, a new, short yet powerful piece by the renowned Mexican/Dutch composer Juan Felipe Waller for prepared Carrillo piano and Fokker organ will be performed. The evident contest between the two instruments will further unfold in an impro-battle, performed by musicians Maarten van Veen and Ere Lievonen. Existing works from the repertoire of these remarkable microtonal instruments will also be featured. The programme includes Music for 16th Tone Piano and Piano by Maarten van Veen and 3 epigrammen voor 31-toonsorgel by Hans Kox. Before these pieces are performed, the Carrillo piano – the newest acquisition of the Huygens-Fokker Foundation – will be presented by artistic director Sander Germanus.
